QUANTITATIVE STRUCTURE-ACTIVITY RELATIONSHIP OF CYTOKININ-ACTIVE ADENINE AND UREA DERIVATIVES

The substituent effect of N6-alkyl and -aralkyl adenines on the promotion of the growth of tobacco callus was analysed quantitatively using physico-chemical substituent parameters and regression analysis.The results indicated an optimum steric condition for activity in terms of the maximum width of the N6-substituents from the bond-axis connecting the N6-atom with its α carbon atom.The electron withdrawing effect of the N6-substituent enhances the activity.The substituent effect on the cytokinin activity of phenyl- and diphenylurea derivatives determined by Bruce and Zwar using the tobacco pith-block assay was also analysed.The results suggest that position-specific steric and hydrophobic effects of aromatic substituents participate in the variation in activity rationalizing the general trend of the activity; meta>para>ortho derivatives, for both series of compounds.The electronic effect is significant for the activity of diphenylureas but not for that of phenylureas which show somewhat different modes of interaction between the two series at the site of action.Based on inferences made from the correlations, hypothetical maps for the mode of interaction of these three sets of compounds at the site of action have been proposed.Key Word Index - Cytokinins; N6-substituted adenines; diphenylureas; phenylureas; structure-activity relationship.
